Specification of Letters Patent.

Patented Jan. 9, 1912.

Application filed March 13, 1911.. Serial No. 614,270.

To allwho'm it may concern:

Be it known that I, THEODOR BAUMERT, a subject of the King of Prussia,residing at Deutsch Lissa, Germany, have invented certain new and usefulImprovements in Oars, of which the following is a specification.

This invention relates to an oar of that type where the rower can sitwith his face turned toward the prow of the boat. The oar is constructedso that it can be quickly lifted up when there is not much room for theoar or when the boat is landing.

In the accompanying drawing the improved oar is shown Figure 1 is a planview of the oar; Fig. 2 is a side view of the oar, the boat being shownin cross section; Fig. 3 is a similar view as Fig. 1, the outer part ofthe oar being lifted; Figs. 4 and 5 show the device for tilting the oarin its two positions; Fig. 6 is an elevation of the thole pin; Fig. 7shows the counter-thole closed and Fig. 8 shows the same open. 1

The handle 1 of the oar is mounted in the thole 2 like a Cardan-joint,by means of the ring shaped swing support 3 which itself is inclosed inthe ring-shaped thole 2. The latter can turn in a horizontal planearound the thole pin 1 like an ordinary thole. The movements of thehandle 1 of the oar as well in the horizontal as in the vertical planeare inversely transmitted to the blade part 6 of the oar. This bladepart 6 is connected with the handle part 1 by a joint 5. The blade part6 of the oar is mounted in a counter thole 7 which is composed of twoparts hingedly connected with each other so that the counter-thole canbe quickly opened and closed. A pin 9 fixed on the part 6 of the oarserves as an abutment. The counter-thole 7 is pivotally mounted in theouter end of an angular support 10 the inner ends of which are pivotallymounted in hingeoints 11 adapted to be lifted with regard to the gunwaleof the boat. The angular support 10 carries a vertical support 12 at theinner end of which a counterweight 13 is fixed which serves forautomatically lifting said angular support 10 and with it the part 6 ofthe oar as soon as the first impulse has been given. The tilting of theangular support is limited by the gunwale of the boat against which thecounterweight 13 butts (Fig. 5).

I claim An improved oar comprising in combination the handle part, athole pivotally mounted in the gunwale of the boat, a ringshaped tiltingsupport for the handle inclosed in said thole, the blade part of theoar, the hinged joint connecting said blade part with the handle,hinge-j oints fixed to the outer surface of the boat, an angular supportfixed with its outer end on said hingejoints, a counter-thole on theapex of the angular support and inclosing the blade part of the oar, avertical support fixed at one end of the angular support and acounterweight fixed at the inner end of said vertical support,substantially as described and shown and for the purpose set forth. Inwitness whereof I have hereunto set my hand in the presence of twowitnesses.

THEODOR BAUMERT.
